JOHN YULE, OF PATERSON, AND WILLIAM A. BOYDEN, OF JERSEY CITY, NEW JERSEY, ASSIGNORS TO THE MONAB & HARLIN MANUFACTURING COMPANY, OF NEW YORK, N. Y.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 236,473, dated January 11, 1881. Application filed December 8, 1880. (No model.)

To all whom it may concern:

Be it known that we, JOHN YULE, of Paterson, in the county of' Passaic and State of New Jersey, and WILLIAM A. BOYDEN, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Lubricator, of which the following is a specification.

Figure l is a side elevation, and Fig. 2 a vertical central section, of our improved lubricator.

The primary object of this invention is to improve the adjusting mechanism of that class of lubricators from which the oil is withdrawn by suction; andthe invention consists, principally, in providing the outlet ofthe lubricator with a tubular valve-carrying screw, through which the oil passes to the journal, and which can be regulated from above without detaching the lubricator from its support.

H eretofore such lubricators were made either with solid valves, around which the oil had to pass, or they were adjustable from below.

In the accompanying drawings, the letter Arepresents the lubricatorshell. B is its cap or cover; C, its base; D, its dischargestem. Within this discharge-stem D is the outletchannel a, which, at or about the middle of its length, is enlarged to form the valveseat b.

Into the bottom of the lubricator is screwed from above a hollow screw, E, the tubular opening of which is open at the upper end, and

terminates at its lower end in one or more lateral discharge-openings, al, and below t-hese lateral discharges the screw is solid and forms the valve e. This valve is contained in the enlarged portion of the discharge-passage of the lubricator, and by turning the screw-valve E, to which access is readily had from above, the amount of oil which the apparatus will discharge is nicely regulated. When the lubricator is properly filled the oil will iiow through the center of the screw E, and through the lateral opening or openings d, down past and beneath the valve e, into the discharge-opening a. While thejournal is at rest no oil can be discharged. When in motion the suction will, whenever there is a vacuum, cause oil to ll the vacuum around thejournal.

IVe do not broadly claim a lubricator with a central screw-valve; but

In a lubricator, the combination of the body A with the hollow screw E, which is open at the upper end, provided with lateral dischargeopening d, and with solid valve e, for operation substantially as described.

This specification signed by us this 6th day of December, 1880.
